401 and the second burner 402 may be seated on the insulator case
31 formed in a single unit, and may have a structure which is
installed inside the case 10 together with the insulator case 31.
The number of the gas burners 40 and a size of each of the gas
burners 40, which are installed at the insulator case 31, are not
limited to the proposed embodiment, and may be variously
applied.
A gas pipe 35 is provided inside the case 10. The gas pipe 35
connects a regulator 51 and a valve unit 52 with the gas burners 40
so that the gas is supplied to each of the gas burners 40.
The gas burner 40 may include the burner port 41 to which the mixed
gas is supplied, a red-heat plate 42 which is seated at the burner
port 41 to be heated by the combustion of the mixed gas, and a
burner holder 44 and a burner cover 45 which supports the burner
port 41 and the red-heat plate 42.
Specifically, the burner port 41 is formed in a cylindrical shape
of which an upper surface is opened, and the red-heat plate 42 is
seated on the upper surface. The mixing tube 34 which supplies the
mixed gas is inserted and installed at one side of an outer portion
of the burner port 41.
The mixing tube 34 may be formed so that a plurality of tubes are
disposed at regular intervals to enable the gas supplied through
the nozzle 33 to be evenly introduced into the burner port 41.
A plurality of nozzles 33 through which the mixed gas is injected
has a structure which is fixed by a nozzle holder to be spaced
apart from the mixing tube 34, and an outlet port of each of the
nozzles 33 is located at a location corresponding to an inlet port
of the mixing tube 34. Therefore, the inlet port of the mixing tube
34 is located at the location corresponding to the outlet port of
the nozzle 33 to be spaced apart by a predetermined gap, such that
air is mixed together by a pressure difference due to a flow of the
gas when the gas is injected through the nozzle 33.
The red-heat plate 42 is seated on an upper surface of the burner
port 41. The red-heat plate 42 is formed to completely shield the
opened upper surface of the burner port 41. The red-heat plate 42
may be formed of a porous ceramic mat, and the mixed gas flowing on
a surface of the red-heat plate 42 may be burned. The red-heat
plate 42 may be formed of another material which is usable to the
gas burner 40.
A spark plug 32 is fixed to and installed at one side of the burner
holder 44. The spark plug 32 serves to ignite the mixed gas in the
gas burner 40, is provided above the red-heat plate 42, and extends
from an outside of the red-heat plate 42 toward an inside thereof
to ignite the mixed gas.
Also, a flame detecting means 321 may be provided at one side of
the spark plug 32. The flame detecting means 321 serves to check an
ignition state of the gas burner 40 through a change in a voltage
or a temperature of the red-heat plate 42, and may be formed in a
module integrally formed with the spark plug 32, and may extend
along with the spark plug 32 from an upper side of the red-heat
plate 42 toward the inside of the red-heat plate 42.
A burned gas guide portion 444 formed to extend backward is formed
at the burner holder 44. The burned gas guide portion 444 may
extend to a rear end of the case 10 corresponding to a location of
the grille vent 21. Therefore, the burned gas generated when the
combustion occurs at the gas burner 40 may be guided to the grille
vent 21 along the burner holder 44, and then may be discharged to
an outside.
The burner cover 45 is provided above the burned gas guide portion
444. The burner cover 45 forms a flow path of the burned gas
flowing through the burned gas guide portion 444, and shields an
opened upper side of the burned gas guide portion 444. A rear end
of the burner cover 45 is formed to be spaced apart from a rear end
of the burned gas guide portion 444, such that cooling air in the
case 10 and the burned gas passing through the burned gas guide
portion 444 are mixed and then discharged.
An insulator for preventing heat of the burner unit 30 from being
transferred to the outside of the case 10 or some areas of the top
plate 20 may be provided between the burner holder 44 and the top
plate 20 and between the burner holder 44 and the insulator case

structure of the fan may be employed according to a user's
selection.
The main fan 61 and the sub-fan 62 enable external air to be
introduced to the inside of the case 10 having a sealed structure,
and simultaneously enable the air inside the case 10 to forcibly
flow and thus to cool the inside of the case 10. The air forcibly
flowing in the case 10 may be discharged to an outside through the
grille vent 21.
The main fan 61 may be provided at a space among the first burner
401, the second burner 402, a barrier 80 and the operation unit 23.
That is, the main fan 61 is located at a location close to the
operation unit 23, the first burner 401 and the second burner 402,
and may cool the operation unit 23, the first burner 401 and the
second burner 402.
The air forcibly flows toward the operation unit 23 by driving of
the main fan 61, and may cool a PCB 231 forming the operation unit
23. A lower surface of the top plate 20 at which the operation unit
23 is located, in particular, the operation part 201 may also be
cooled by the main fan 61. Therefore, through cooling of the PCB
231, the operation unit 23 and the operation part 201 of the top
plate 20 may be cooled so that the user does not feel discomfort
due to heat generated when operating the operation part 201 of the
top plate 20.
By the driving of the main fan 61, the air outside the case 10 is
introduced, and forcibly flows radially centering on the case 10,
and some of the air may flow along perimeters of the first burner
401 and the second burner 402, and thus heat from the first burner
401 and the second burner 402 does not stay at the inside of the
case 10, but is discharged to the outside.
Therefore, a space of the internal space of the case 10 at which
the gas burner 40 is provided may be cooled by the driving of the
main fan 61, and may also protect electronic components in the case
10, i.e., the PCB 231 and sensors forming the operation unit
23.
The sub-fan 62 serves to cool the valve unit 52 which is configured
with an electronic valve such as a solenoid valve provided at one
side in the case 10, and may be provided at one side of an edge of
a rear half portion of the case 10. The sub-fan 62 is provided
inside a space partitioned by a side barrier 63, and by the side
barrier 63, a space in which the valve unit 52 is disposed may be
partitioned from the space in which the gas burner 40 is
provided.
Therefore, by driving of the sub-fan 62, the air outside the case
10 may be introduced into the space partitioned by the side barrier
63, and the valve unit 52 may be cooled separately from the space
in which the gas burner 40 is disposed.
Specifically, the side barrier 63 may be fixed to and installed at
a bottom surface of the insulator case 31, and may be installed so
that both ends are in contact with one of both of left and right
side surfaces of the case 10 and a rear surface of the case 10.
The side barrier 63 may generally include a fan seating portion 631
providing a surface on which the sub-fan 62 is seated, and an
extending portion 632 which partitions the internal space of the
case 10.
Specifically, the fan seating portion 631 is formed in an
approximately triangular plate shape, and also formed to be in
contact with an upper surface of a fan installing portion 11. The
sub-fan 62 may be fixed to the fan seating portion 631, and the
side barrier 63 installed at the insulator case 31 may be assembled
inside the case 10 together with the insulator case 31.
The fan seating portion 631 is formed in a right-angled triangular
shape, and also formed so that one inclined end of the fan seating
portion 631 is connected to the extending portion 632, and the
other end is in close contact with a side surface of the case 10.
Therefore, the side barrier 63 may be maintained in a stably fixed
state without vibration due to an air flow.
The extending portion 632 is formed to be vertically bent upward
from the inclined end of the fan seating portion 631, and also
formed to be fixed to a lower end of the insulator case 31 and to
partition the internal space of the case 10.
The extending portion 632 extends along the inclined end of the fan
seating portion 631, may further extend outward, and may include a
first extending portion 632a which partitions the case 10, and a
second extending portion 632b which is bent from an end of the
first extending portion 632a and partitions a side exhaust port
315.
The first extending portion 632a is formed to partition a space
between the insulator case 31 and the case 10, and to guide the
flow of the air blown by the sub-fan 62.
The second extending portion 632b is bent from the end of the first
extending portion 632a, passes through the side exhaust port 315,
and extends to be in contact with the rear end of the case 10.
Accordingly, by the second extending portion 632b, the side exhaust
port 315 may be divided into both of left and right sides based on
the second extending portion 632b, and the cooling air flowing
along the first extending portion 632a may be independently
discharged through the side exhaust port 315 partitioned by the
second extending portion 632b.
A bent portion 633 which is bent outward may be further formed at
an upper end of the first extending portion 632a. The bent portion
633 is in contact with a lower surface of the insulator case 31. A
fastening member such as a screw and a bolt may be fastened to the
bent portion 633 and the insulator case 31, and the side barrier 63
may be fixed and installed.
Each of the main fan 61 and the sub-fan 62 is installed to be in
close contact with an opening formed at the bottom surface of the
case 10. Since the case 10 has a structure in which a remaining
portion of the case except a portion at which the main fan 61 and
the sub-fan 62 are installed is sealed, the air introduced into the
case 10 may be introduced only through the main fan 61 and sub-fan
62.
The internal space of the case 10 may be partitioned by the barrier
80. The barrier 80 extends from a front end of the case 10 to the
rear end of the case, and partitions the internal space of the case
10 into both of left and right sides. The gas burner 40 is provided
in one side space partitioned by the barrier 80, and an induction
burner 70 is provided in the other side space.
The induction burner 70 is provided at one side of a space
partitioned by the barrier 80. The induction burner 70 may include
an induction heating part 71 which is installed at a lower side of
the top plate 20 and provides an alternate magnetic field to a
cooking container put on the top plate 20, and an induction case 72
which is disposed at a lower side of the induction heating part 71
to support the induction heating part 71 and in which elements for
operating the induction heating part 71 are accommodated.
An inverter module 722 which supplies AC power to the induction
heating part 71, and a switching element which is disposed as one
of electronic elements of the inverter module 722 at one side of
the inverter module 722 and generates high temperature heat may be
provided inside the induction case 72. At this point, the switching
element may be formed in a coupled state to a cooling means such as
a heat sink. A control part 721 for controlling an operation of the
induction burner 70 may be provided at one side of the induction
case 72.
The induction case 72 is opened in forward and backward directions,
and an induction fan 64 which cools an inside of the induction case
72 is provided at an opened front of the induction case 72.
Therefore, the control part 721 and the inverter module 722 in the
induction case 72 may be cooled by driving of the induction fan 64.
In addition, the inside of the case 10 may be cooled by discharging
the air in the internal space of the case 10, in which the
induction burner 70 is provided, to the outside.
The insulator case 31 and the induction case 72 which are provided
at both of left and right sides of the barrier 80 may be fixed to
and installed at the barrier 80. To this end, coupling portions
723, 724, 311 and 312 for coupling with the barrier 80 may be
further formed at the insulator case 31 and the induction case 72,
respectively. The coupling portions 723, 724, 311 and 312 may be
integrally formed with the insulator case 31 and the induction case
72, and may be formed by coupling a separate member.
A plate bracket 24, an extending portion 241 included in the plate
bracket 24, a top plate fixing portion 242, a bracket fixing
portion 243, an operation unit fixing portion 244 and a fixing
portion 245 which are not described will be described below in
detail.
As illustrated in FIG. 5 and FIG. 6, the barrier 80 may include a
partitioning portion 81 which extends from the front end of the
case 10 to the rear end thereof, a plate supporting portion 82
which is bent from an upper end of the partitioning portion 81 and
supports the lower surface of the top plate 20, and burner fixing
portions 83 and 84 which are bent from a lower end of the
partitioning portion 81, coupled to the insulator case 31 and the
induction case 72 and fix the gas burner 40 and the induction
burner 70.
The partitioning portion 81 may be formed to be bent several times
and to allow a smooth air flow without interference with the gas
burner 40 and the induction burner 70, and both of extending ends
are in contact with a front surface and a rear surface of the case
10, respectively.
The plate supporting portion 82 is formed to have a predetermined
area, and may be formed to be bent outward from the upper end of
the partitioning portion 81. Therefore, the plate supporting
portion 82 may be bonded or attached to the lower surface of the
top plate 20, and thus may be fixed thereto. Accordingly, the
barrier 80 may be fixed to and installed at the top plate 20.
The burner fixing portions 83 and 84 are formed to be bent outward
from the lower end of the partitioning portion 81, and also formed
to extend in a predetermined length. The screw holes 831 and 841 in
which the fastening member is fastened may be formed at the burner
fixing portions 83 and 84. Therefore, the coupling portions 311,
312, 723 and 724 formed at the insulator case 31 and the induction
case 72 are formed to be fixed to the burner fixing portions 83 and
84 by the fastening member S, respectively. For example, the
coupling portions 311, 312, 723 and 724 of the insulator case 31
and the induction case 72 may be fixed to the burner fixing
portions 83 and 84 by the fastening member S such as the screw.
The numbers and locations of the coupling portions 311, 312, 723
and 724 and the burner fixing portions 83 and 84 are not limited to
the described implementation, and if necessary, a plurality of
burner fixing portions 83 and 84 may be formed at any locations of
the barrier 80, and the coupling portions 311, 312, 723 and 724 may
be formed at locations corresponding to the burner fixing portions
83 and 84, respectively.
The side surfaces of the insulator case 31 and the induction case
72 close to the barrier 80 may be fixed by the barrier 80, and
outer ends opposite thereto may be fixed by the plate bracket 24
provided at the top plate 20.
As illustrated in FIG. 7 and FIG. 8, the top plate 20 is seated on
the top frame 22, and forms a surface on which food is seated, and
the grille vent 21 is provided at a rear of the top plate 20, and
the plate bracket 24 may be provided at the top plate 20. The plate
bracket 24 is provided at the lower surface of the top plate 20,
and one pair of plate brackets 24 may be provided at both of left
and right sides facing each other. When the top frame 22 on which
the top plate 20 is seated is seated on the case 10, the plate
bracket 24 is located inside the case 10.
Specifically, the plate bracket 24 may include the extending
portion 241 which extends along the lower surface of the top plate
20, the top plate fixing portion 242 which is formed at an upper
end of the extending portion 241 to be fixed to the top plate 20,
and the operation unit fixing portion 244 which is bent inward from
a front end of the extending portion 241 to fix both ends of the
operation unit 23 provided inside the case 10.
The extending portion 241 extends along each of both side ends of
the top plate 20 in forward and backward directions, and the top
plate fixing portion 242 is formed to extend inward from a rear end
of the extending portion 241. The top plate fixing portion 242 is
formed to have a predetermined area, and provides a stable coupling
force to the top plate 20. That is, an upper end of the plate
bracket 24 including the top plate fixing portion 242 may be bonded
or attached to the lower surface of the top plate 20, and thus may
be fixed thereto.
The bracket fixing portion 243 which is bent downward is formed at
the top plate fixing portion 242. Each of both of the bracket
fixing portions 243 and 246 is formed to extend to one side of each
of the insulator case 31 and the induction case 72, and may be
fixed by the fastening member such as the screw passing through and
fastened to the insulator case 31 and the induction case 72.
Therefore, the insulator case 31 and the induction case 72 have a
structure which is fixed to the plate bracket 24.
Due to such a structure, both ends of the gas burner 40 and the
induction burner 70 may be fixed to the barrier 80 and the plate
bracket 24, respectively. Since the barrier 80 and the plate
bracket 24 are attached to the top plate 20, the gas burner 40 and
the induction burner 70 may be attached to the top plate 20 in a
module type.
The operation unit fixing portion 244 may be extend inward from an
end of the extending portion 241, and may be fixed to each of both
of side surfaces of the operation unit 23. Accordingly, the
operation unit 23 may also be coupled to the top plate 20 in a
module state. The fixing portion 245 which extends perpendicularly
to the operation unit fixing portion 244 and is in contact with the
operation unit 23 to further stably fix the operation unit 23 may
be further formed at an end of the operation unit fixing portion
244.
As illustrated in FIG. 9, when a user operates the operation unit
23, and inputs an operation of the gas burner 40, opening and
closing of the valve unit 52 is determined according to an
operating signal, and thus the gas may be supplied to the desired
gas burner 40.
When the gas is mixed with the air, and then the mixed gas is
supplied to the gas burner 40, the mixed gas is ignited by the
spark plug 32, and the combustion occurs at the red-heat plate 42,
and thus the red-heat plate 42 may be heated. By heating of the
red-heat plate 42, a radiant wave may be emitted from the red-heat
plate 42 to an outside, and thus may heat food or a container
including the food which is seated on the top plate 20.
The user may control heating power of the gas burner 40 through an
operation of the operation part 201, and may also visually check an
ignition state of the gas burner 40 and a heating state through the
top plate 20 because visible rays are included in the radiant
wave.
The main fan 61 and the sub-fan 62 are driven along with the
ignition of the gas burner 40. By the driving of the main fan 61,
the air in the case 10 may be suctioned toward the main fan 61. The
suctioned air is discharged radially centering on the main fan
61.
Some of the air blown through the main fan 61 flows toward the PCB
231 of the operation unit 23, and thus the PCB 231 is continuously
cooled to be normally operated, and also a front half portion of
the top plate 20, particularly, the operation part 201 may be
cooled.
Some of the air blown through the main fan 61 may pass between the
first burner 401 and the second burner 402, may flow to a rear
side, and then may be discharged through the grille vent 21.
As described above, by rotation of the main fan 61, the air in the
case 10 continuously cools the front half portion of the top plate
20 at which the operation unit 23 is located, and the air close to
the first burner 401 and the second burner 402 is discharged, and
thus an internal temperature of the case 10 is prevented from being
increased to a preset temperature or more.
When the sub-fan 62 is driven, the air outside the case 10 may be
introduced into the case 10, and may independently cool the
internal space of the case 10 partitioned by the side barrier 63.
That is, due to the driving of the sub-fan 62, the valve unit 52
may be cooled independently.
The heat generated upon the combustion of the gas burner 40 may be
effectively cooled by the main fan 61, and then may be discharged
through the grille vent 21. Also, the heat may be prevented from
being introduced toward the induction burner 70 partitioned by the
barrier 80.
As illustrated in the FIG. 10, when the user operates the operation
unit 23, and inputs an operation of the induction burner 70, the
control part 721 and the inverter module 722 are driven according
to an operating signal, and the alternate magnetic field is formed
at the induction heating part 71, and the container including the
food which is seated on the top plate 20 may be
induction-heated.
Meanwhile, at the same time when the induction burner 70 is
operated, the induction fan 64 is operated, and the induction fan
64 blows the cooling air from a front of the induction case 72
toward a rear of the induction case 72.
The air blown toward the rear effectively cools the inverter module
722 generating heat, while passing through the induction case 72,
and also cools other elements including the control part 721. In
addition, some of the air blown by the induction fan 64 discharges
the air in the internal space of the case 10, in which the
induction burner 70 is accommodated, to the outside through the
grille vent 21.
As described above, when the gas burner 40 and the induction burner
70 which are provided at both of the spaces partitioned by the
barrier 80 are operated, cooling structures may be formed
independently, and the cooling air in each of the spaces may not be
introduced into the adjacent space by the barrier 80, but may be
discharged, and thus the stable operation of the induction burner
70 may be ensured.
In some implementations, the combination type cooker may not be
installed at the furniture such as the sink in a built-in method,
but may be independently installed at a separate case.
As illustrated in FIG. 11, a combination type cooker 1 may be
formed to be seated on an outer case 10' which forms an exterior
while the top plate 20 and the case 10 are assembled.
In some implementations, the top plate 20 may be directly installed
at the outer case 10', and all of the elements including the burner
unit 30 which are disposed in the case 10 may be installed inside
the outer case 10'.
Although implementations have been described with reference to a
number of illustrative implementations, it should be understood
that numerous other modifications and embodiments can be devised by
those skilled in the art that will fall within the spirit and scope
of the principles of this disclosure. More particularly, various
variations and modifications are possible in the component parts
and/or arrangements of the subject combination arrangement within
the scope of the disclosure, the drawings and the appended claims.
In addition to variations and modifications in the component parts
and/or arrangements, alternative uses will also be apparent to
those skilled in the art.
